It turns out that today’s promo was just the start of a three-day event that spans from now until Sunday, and will bring a new free phone each day.

Tomorrow it’s going to be the BlackBerry Torch 9800 for AT&T. $0, with a two-year agreement required. The twist here is that this won’t be one-day-only affair as with the iPhone – rather, the Torch will stay free at Best Buy throughout the entire month of December.

On Sunday, you’ll also be able to get yourself a T-Mobile BlackBerry Curve 9300, also for $0. Again, a new 2-year contract is needed. And this offer will also extend all the way to the end of December.

So if you were after a new BlackBerry smartphone, perhaps you should check out Best Buy, as their prices are now the best for a couple of them.
